Flashcards in Photosynthesis Deck (37):
1
All life on Earth depends on the flow of _____
Light energy
2
The source of energy in photosynthesis is from the _____
Sun
3
Autotrophs:
Organisms that can make their own food
4
Heterotrophs:
Organisms that cannot make own food
5
How do autotrophs get food
Use light energy from the sun to produce food in the form of glucose/sugar
6
Examples of autotrophs
Green plants, some bacteria, some protists
7
Examples of heterotrophs
All animals, fungi
8
ADP:
Adenosine diphosphate
9
ATP:
Adenosine triphosphate
10
What is significance of the third phosphate in ATP
To store excess energy
11
Three parts of ADP/ATP
Adenine, ribose, phosphate groups
12
Cellular activities that would require the energy of ATP
Active transport, cell division, DNA synthesis, spindle formation for DNA replication
13
Why is it important for ATP to become ADP
Use extra phosphate group as a source of energy
14
How does ATP turn into ADP
The phosphate group breaks off
15
How does ADP become ATP
Adds a phosphate group - energy comes from glucose
16
What is equation for photosynthesis
6CO2 + 6H20 yields C6H12O6 + 6O2
17
How does chlorophyll make a plant appear green
The chlorophyll captures red and blue lights and then reflects green wavelengths
18
What plant structures control the passage of H2O out of the cell and CO2 into the cell
The stomata
19
Is carbon dioxide produced during photosynthesis
No
20
Are all parts of the plant able to carry out photosynthesis
No
21
Life on earth is dependent on photosynthesis for what two things
Oxygen and glucose
22
Why do autotrophs depend on heterotrophs
Carbon dioxide
23
Where does the plant take in water
Through roots
24
How does the plant get carbon dioxide
Through the stoma of the stomata
25
Name of waxy layer on leaf that prevents water loss
Cuticle
26
What is any substance that absorbs light called
Pigment
27
Name of cells in leaf that are primary photosynthetic layer of the leaf
Pallisade
28
Name of middle portion of leaf
Mesophyll
29
Pores on underside of the cell are called
Stoma
30
What carries water to the leaves from the roots
Xylem
31
What carries food out of the cell to all other parts of the plant
Phloem
32
Plants absorb the sun's energy with _____
Light absorbing pigments
33
Chlorophyll a:
Blue-green
34
Chlorophyll b:
Yellow-green
35
What parts of the cell contain chloroplasts
Pallisades and spongy cells
36
What are the guard cells
Stomata
